Hey Roger, how did your end of season cleanup go? I forgot to give my end of 1st season update. Bottom line very impressed with my Edge 750HD. Very easy to use, operate and clean. Easily achieved 1,000+ degree burn temps each cycle which seemed to keep creosote accumualtion to a minimum. Never had more than a fine powdery coating on the rear exchangers which are easily seen and accessed by opening the rear hinged door. Taking out the side air channels for end of season cleanup (only time I removed all heating season) was very easy, again some powder accumulation and back right corner had a little creosote buildup that easily scraped out. Probably because I neglected the back corners a little, but not enough to effect perfomance. The new stepper motors worked great and I had almost no creosote built up in the bottom of those elbows. So right now she is scraped out, cleaned out, vacuumed out, put back together and has a bucket over the chimney and ready to go next season. I would have to give it a 10 out of 10 on a rating scale. Did everything I expected and great improvement on maintenance requirements over the Eclassic. I had no controller or water level float switch problems with mine, but my dealer buddy did recommend I swap out my plastic float switch for the new stainless float switch they use now during the off season.
